I want this website template to look the same when I uploaded to my host as it does on the creators example website.

Here is the example template: https://html5up.net/uploads/demos/zerofour/

Here is the exact same code loaded onto my host: https://curtiscolevideo.com

I am working with the template website and the template on the hosts page looks perfect but when I download the exact same template and load it on my host it looks quite a bit different with smaller fonts and a few other small changes. If the file is exactly the same with same HTML and CSS what else could be making these weird changes?

Here is the template and exact code I am loading: https://html5up.net/uploads/demos/zerofour/
